Summary
With a height of 29 feet and a storage capacity of 512 acre-feet, the dam serves as a vital resource for the local community. Situated on a tributary to Little Medicine Creek, Overlook is managed by the Rock Island District and falls under the jurisdiction of the state of Missouri.
Despite its low hazard potential and unlisted foundations, the condition of Overlook has not been officially rated. The dam, with a normal storage capacity of 319 acre-feet, covers a surface area of 33 acres and plays a crucial role in water resource management in the region. While there have been no recent inspections or updates on emergency preparedness, Overlook continues to serve its primary purposes efficiently.
With its strategic location and modest scale, Overlook represents a key infrastructure for fire protection and water supply. Although its risk assessment and management measures are not specified, the dam remains a cornerstone for maintaining water resources in the area. As an essential component of the local ecosystem, Overlook contributes to the overall climate resilience and water security of the region.

Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
